Now, three years after her first transplant (she has since had another), Tillemann-Dick has given a second talk, “Discourses from the undead,” filmed at TEDxMidAtlantic in December. In the talk above, she takes a stark look at death. sharing the vivid dreams that she had while she was in an unconscious state after her surgery — a time when her doctor said that survival was unlikely. Having “spent many a night in death’s guesthouse,” Tillemann-Dick shares meaningful lessons that she believes to be from the next world, and gives thanks.

“While [death’s] sting is real, good can come from it,” she says. “Death is as much a part of life as love, birth and happiness.”

Far too few people are organ donors, and Tillemann-Dick attributes this not to disregard but to our lack of conversation about death. She says it’s time to talk about death. Will you join her?
